Azeotropes
Azeotrope is a particular mixture (two or more miscible liquids) which does not change the composition during the distillation. This mixture has two different types: a high-boiling azeotrope and a low-boiling azeotrope. In a high-boiling azeotrope (Figure 3), if a maximum occurs in the phase diagram, the liquid is stabilized due to favorable interactions between A and B molecules.
